Question

A car traveling at a velocity of 25 m/s increases its velocity to 30.0 m/s in 10.0 seconds. What is the magnitude of its acceleration?

Answer 1

Explanation: vf-vi/t = a

a=30m/s -25 m/s/10 s

a =5m/s /10s

a =1/2 m/s²

Answer 2

Hi there!

We can use the kinematic equation:

vf = vi + at

vf = final velocity (m/s)

vi = initial velocity (m/s)

a = acceleration (m/s²)

t = time (sec)

Rearrange to solve for acceleration:

(vf - vi)/t = a

(30 - 25)/10 = 5/10 = 0.5 m/s²
